Cosmic Watch, It’s an app that is an interactive 3D tool. You can use it as a realtime worldclock, time travel machine, an astrolab, an antikythera mechanism, an orrey, an armillary sphere, or an astral-chart generator.

The unique thing about the clock face is its ecliptic view around the planet. The complex mechanism of telling time is at the touch of your hands with the Cosmic Watch App. A fun learning tool to explore the relation between time and the celestial dynamics.

I had my husband check this one out for me and he thought that it was pretty cool!
